To fully utilize the energy efficiency of lithium batteries and extend their service life, attention should be paid to the maintenance and storage methods of lithium batteries. The specific precautions are as follows:
1. Lithium batteries should be charged with 50% -80% of their battery capacity when not in use for a long time. They should be removed from the instrument and stored in a dry and cool environment. The battery should be charged every three months to avoid excessive storage time, which may lead to low battery capacity due to self discharge and irreversible capacity loss
2. The self discharge of lithium batteries is affected by environmental temperature and humidity. High temperature and humidity can accelerate the self discharge of batteries. It is recommended to store the batteries in a dry environment at 0 ℃ -20 ℃
3. Avoid mixing batteries with other conductors. The battery has no protection and is mixed with metal objects such as keys in backpacks, pockets, etc. During movement, the conductor briefly or for a long time contacts the positive and negative poles of the battery to form a closed circuit, which can cause a short circuit and cause the battery to overheat, burn out, leak liquid, etc
4. Avoid unprotected use after the battery is peeled. Because the battery relies on the insulation of the positive and negative electrodes by the battery skin, a short circuit may occur when the battery skin is broken or the battery cells are completely peeled off before installing a flashlight
5. Avoid disorderly storage of multiple batteries. In the storage of large quantities of batteries, they are not neatly stacked, and there are no insulated objects between each stack of batteries. Disorderly stacking can cause some batteries to be connected in a closed loop and short circuited
6. It is prohibited to store in places with strong static electricity and strong magnetic fields, otherwise it may damage the battery safety protection device and bring unsafe hazards
7. If the battery emits any odor, heat, discoloration, deformation, or any abnormalities occur during use, storage, or charging, the battery should be immediately removed from the device or charger and stopped
8. Abandoned batteries should be wrapped with insulating paper around the electrodes to prevent fire and explosion
